Phone dialing numbers by itself

I have Polycom phones that are self-dialing clients and intercoms.

This is very aggravating as this process never stops. Client and customers are getting non-stop calls from our phones and there is nothing we can do to stop the calls. It is as if the phones have been hacked or Casper the ghost is in our office.

Technical Support is not helpful at all, as I keep getting the same girl who is reading answers from a manual...

Is anyone else having this issue?

I have heard of this a few times, but the only way I can imagine it happening is if your network is not configured correctly/securely.  Do you work on the network and know how your firewall is configured?  You should have *no* inbound port forwarding to phones.  If your phones are visible via the public internet they will be hacked.  I would start by reviewing your firewall settings or asking your network person to.

Our network is protected by Fortinet Firewall. No inbound ports have been forwarded to the phones.

Are these phones purchased from RC or you provided them?

I would review this or share with your Fortinet vendor: https://success.ringcentral.com/articles/RC_Knowledge_Article/9233
Notably:
In a stateful firewall, no inbound ports need to be opened because they are automatically opened upon a reply to outbound traffic initiated by the RingCentral endpoint in the local network.

The phone were rented from RC.

As stated, there are no ports opened to the phones. We have one phone that was re-provisioned as it was self dialing. It is doing it again... this time we took videos of the issue. RC has sent out a replacement phone....

This is strange indeed.  If you haven't opened a support case yet, can you please do so?  Please include the most recent samples (dates, times, #s etc) in the case notes.

I have this issue with a VVX-500 purchased from Ring Central. It does it every day and dials my other phone and records whatever is going on in the room with the other phone until the recorder for a voicemail stops. Then you can go back and listen to what was recorded. Strange! Today, 12/29/17, it has done it 5 times.

We had this problem with VVX-500's as well. The fix was to remove the extensions from the HUD. According to support, there is a bug in the 500's soft-keys that causes this anomoly.

I personally believe (no proof, but strong belief) that RingCentral could stuffing minutes into user accounts with their apps by performing auto dials.  On another account, I received over 2500 calls from 1800 numbers in 200 area codes TO A FAX NUMBER.  Multiple attempts on multiple days from the same number - WTF?  Every call was 48 to 51 seconds.  No less, no more.  Majority of calls were from mobile numbers.  I will be calling these numbers to see if they are RingCentral accounts.

Oh - and no, they will not refund the overages even though all of these mobile numbers are calling a fax account and RC is charging "PAGE" overages due to the thousands of 48 to 51 second calls.

Any RC fans out there that could explain this?  A brand new account.. thousands of mobile phone calls, multiple numbers, multiple attempts, different days... TO A FAX.

I have no explanation from RC.

Google traffic pumping. It explains what is happening to your toll free number.

So google traffic pumping?  How does calling my fax 2K+ times benefit google? The calls are from carriers such as Metro PCS, Verizon, AT&T Wireless, Cricket, and even local AT&T IP.

I don't believe now that it has anything to do with ring central app.  I'm reviewing other logs on a new account with zero calls inbound.    My search continues although now I wonder if they assigned me a heavily used number and these are remnant calls.

I meant google the term ‘traffic pumping’. It is an age old scam of dialing toll free numbers through rural telcos. Regulations require larger carriers to pay the rural carriers more the minutes and they spilt the profit with the group pumping the calls. Similar to the free conference services offered by rural telcos.

Thank you for that clear description.  Oddly, carrier lookups on these numbers return to major mobile carriers - would that benefit the rural carriers in any way?

Here is a article and podcast about it. It is really interesting even though the practice is so annoying if it happens to you. http://www.awardconsulting.net/traffi...

The numbers you see are likely spoofed so you can’t trust any caller I’d you see. Sometime in the future hopefully this will change with a mix of technology and legislation/regulation.
